2020 LowDown Showdown Winner – Team Aequitas


Each year of the LDSd competition, we ask participating teams to take on a new challenge in building performance analysis. For 2021 the competition will ask teams to expand their comfort zone and take on the challenges of a tropical climate with particular challenges for resiliency and “near net zero” design. The competition will also require teams to use their creativity to develop schemes for engagement of the building & its occupants with the community.

The 2021 LDSd model building will be located in Puerto Rico. Participating Teams will design a 75,000 sf, residential care center located at a site on the island to be chosen by each team. The building will contain residences, offices, amenities and clinical spaces.

Here’s your chance to join an integrated team that will compete for fun and prizes in the annual LowDown Showdown modeling competition. Sign your team up today or sign up as an individual participant and we will put you on a team! Bring your imagination and analytical skills to the party and create the prototype building of the future! 

  • Building Model Description

    General Description:

    The 2021 LDSd model building is a residential care center which includes residential living spaces, amenities, a small clinic for residents, a kitchen with dining room and limited office & meeting space for facility staff. The new building is to be designed for efficiency and sustainability for both the short and long term with an emphasis on net-zero energy operations, resiliency, and community engagement.

    Model Building Location:  Puerto Rico

    65,000 sf of indoor space + 10,000 sf of outdoor space (new construction) 

    • 55,000 sf of residential
    • 1,500 sf office & conference
    • 1,500 sf of kitchen (light commercial)
    • 4,000 sf of dining space
    • 2,500 sf of clinic & PT space
    • 1,000 sf lobby
    • 1,500 sf circulation spaces
    • 8,000 sf amenities (shared spaces for use of residents):  Amenities – exact mixture of amenities to be determined by design teams but should be for use of residents from 8am till 10pm
